摘要： The invention relates to a method for the treatment of circulating water in paint booths, whereby the paint particles are dispersed by adding dispersants selected from the group consisting of: a) homopolymers and copolymers based on maleic acid, acrylic acid and/or methacrylic acid with a molar mass ranging between 2500 and 500 000; b) non-ionic surface active agents; c) anionic surface active agents, whereby no polyaspartic acid is additionally added to the circulating water in said case and d) inorganic or non-polymeric organic complexing agents and mixtures thereof, their total concentration ranging from 0.01 to 2.0 percent by weight in relation to the circulating water. According to said method for the treatment of circulating water in paint booths, the circulating water has a hardness of at least 2° measured in accordance with the German water hardness system. By adding dispersants in a concentration ranging between 0.001 and 2.0 percent by weight in relation to the circulating water, the paint particles are dispersed in such a way that they have a mean particle size of less than 20 νm determinable by laser diffraction.

摘要： An antifoam agent contains a combination of (a) unsaturated or saturated, linear or branched carboxylic acids with 10-22 C atoms; (b) polypropylene glycols and/or ethylene/propylene oxide block polymers with molar masses in a range of 1000 to 5000; (c) primary alcohols with 5-16 C atoms and/or glycerine fatty acid esters in a weight ratio of 1-30 parts per weight (a) to 0.1-50 parts per weight (b) to 50-90 parts per weight (c). Also disclosed is its use for defoaming paint coagulation baths.

摘要： Selon un procédé de traitement (recyclage) de caillots de laque contenant de la laque pulvérisée résiduelle et des coagulants contenant du silicate stratifié, les caillots de laque contenant du silicate stratifié sont séchés sous vide, traités à de basses températures puis broyés. Les caillots de laque ainsi recyclés sont utilisés comme composants de base, comme agrégats ou comme charges dans des laques et peintures, dans des matériaux de construction ou d'étanchéité, dans des masses de protection du bas de caisse de voitures ou des adhésifs.

摘要： Means and method for the treatment of the circulating water in painting booths, whereby the paint particles are dispersed by addition of emulsifiers, comprising a mixture of end-group terminated fatty alcohol alkoxylates with 8 to 22 C atoms in the fatty alkyl group and 3 to 60 alkylene oxide units, terminated at the end group with a C1- to C5- alkyl group with one or several of the following co-emulsifiers: a) homo- and co-polymers based on maleic acid, acrylic acid and/or methacrylic acid with a molecular mass in the range 1,000 to 500,000, b) non-ionic detergents which are not end-group terminated, c) anionic detergents, d) inorganic or non-polymeric organic complexing agents and e) polymers or co-polymers of amino acids.

摘要： A process is disclosed for detaching and coagulating paints and other organic coating agents, in particular water-based lacquer systems ('water lacquers') in circulation waters of water-spray separators for spray painting installations, in which lacquer coagulating agents known per se are added to the circulation waters. The process is characterized in that the hardness range of the circulation waters is set between 0 to 1.0 mmol/l alkaline-earth metal ion equivalents.
